We are considering to replace our ancient gas boiler with a air-to-water heat pump. They sound good and reliable whereever you read, BUT some and in parrticular the one I have got my eye on, requires 3-phase power supply.
Our house is an old house with standard domestic supply and a split load fuse board. How much hassle and what cost would I be looking at - if there is anything like a standard figure - if I wanted to have 3-phase electrics installed?
